Here's a very interesting article about a teacher who uses blogging in his teaching. Instead of telling his students to "hand their papers in to me, the teacher," he has them post entries and respond to other's posts on blogs created for the class. Their discussion on the book The Secret Life of Bees eventually included the author of the book herself! The students soon found that their blog was the number one result for a Google search on the book, surpassing even the author's website. He believes that the Internet and the right software tools will "liberate students from the anachronistic traditional classroom" and become "self-motivated learners and creators, driven by their own passions.
